.SELF-MEASURING PUMP.

SPECIFICATION forming part of Letters Patent No.'534,464, dated February19, 1895, Application yfiled June 28,1894. Serial No. 515.997. (Nomodel.)

To all whom it may concern:

Be it known that I, SYLVANUS F. BOWSER, a citizen of the UnitedStates,'residing at Fort Wayne, in the county of Allen and State ofIndiana, have invented a `new'and useful Self- Measuring Pump, of whichthe following is a specification.

This invention relates to self-measuring pumps; and itlhas for itsobject to eifect certain improvements in pumpsof that character whereinmeans are provided for accurately gaging the quantity of liquid to beelevated without theuse of supplemental measuring devices.

To this end the main and primary object of this invention is to providecertain improvements in the operating mechanism for pumps of thatcharacter especially employed in lifting oils and other heavy liquids,whereby the quantity of oil may be properlyand accurately gaged, and atthe same time registered, when large quantities are being pumped.

With these and otherobjects in view, which will readily appear as thenature of the invention is better understood, the Vsame consists in thenovel construction,combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

In the drawingsz-Figure l isa side elevation of a storage tank, partlyin section show-y ing my improved pump used in connection therewith.Fig. 2 is an enlarged detail in perspective of the pump operating mechanism. Fig. 3 is a central vertical sectional view of the constructionshown in Fig. 2. Fig. 4. is a transverse sectional; view on the line ofFig. 3. Fig. 5 is a detail sectional view on the line y-g/ of Fig. 4.Fig. 6 is a similar view on the line .e-z of Fig. 4. Fig. 7 is a detailin perspective lof `the adjustable stop collar carrying the slidingstop-stud.

Referring to the accompanying drawings, A represents an ordinary storagetank in connection with which the herein described pump is preferablyemployed, and this storage tank is usually intended to be arranged inthe cellar of a store or below the iioor thereof whereby thecontents,rwhich are oil or lother liquid, may be conveniently pumped upinto the store-room by the operator. This storage tank A, is provided atthej'bottom thereof with a drop pump-pocket B, which is of a.

depth sufficient to accommodate the cylinder of a pumping apparatus,said pocket usually being about eighteen inches deep. The pocket B,extends below the plane of the tank bottom so that the entire liquidcontents of the tank can be substantially drained by the pumping devicesemployed in connection with the tank, the cylinder C of such pump beingadapted to be seated in the said pocket,

and at its upper edge the pocket is entirely encircled or surrounded bythe surrounding rim-Bange extended upwardly from the bottom of the tankaround the upper edge ofthe pocket. The upwardly extended rimange isusually about one inch high and serves to keep back all the sedimentthat would otherwise naturally drain into the pumpspocket and clog upand interfere with the free working of thepump.

The pump cylinder C, is of the ordinary construction, and in the presentinvention is preferably bolted to the lower end of the frame upright D,which is of a length sufficient to extend above, the iioor andto a con-Y venient height for easily operating the pump,

land said pump cylinder C, at the lower end of said upright, hasconnected to the lower end thereof the pump discharge pipe E, whichrises parallel with the frame upright to substantially the same heightas the same. said pump cylinder O, accommodates therein the piston headE,`to whichl is attached the lower end ofthe pump rod F, working throughthe top of the tank and the iioor above which the apparatus projects,and having attached The to the upper portion thereof the vertical rackbar G.' The rack bar G, is provided at its upper and lower ends withthe'off-standingcollars H, embracing the pump rod and one of whichcollars receives the set screw I, to

clamp the said rack bar in pump rod.

The rack bar upper end of the pump rod position on the is guided to movethrough a top guide open ing J, in the o-standing bearing bracket K,having an inner iianged end lc, bolted at one side of the frame uprightD, at the upper end thereof. The said off-standing bearing bracket K, isof a substantially hollow construction having the opposite bearingsides- L, from the inner faces of which project inwardly extending guidelugs Z, disposed at IOC) one side of the attached rack bar G, to assistin holding the pump rod steady in its vertical reciprocations, While -atthe outer end of the bearing bracket is located a` top pipe opening M,to receive the extreme upper end of the pump discharge pipe E, which isheld firm in this bracket by a set screw m, engaging a threaded openingat the outer end of the bracket and impiuging against the, said pipe.

A reciprocatory movement is communicated to the pump rod from themeshing cog pinionN,mountedon the short operatingshaft O, journaled inthe opposite bearing, sides of the oft-standing bracket- K, and one endvof said short operating shaft O, projects through, the short circularbearing collar P, projected from the outer face of one of the bearingsides of the brackets, and this projecting end of the short operatingshaft is squared to removably receive one end of thecrank handle Q. Atthe end which is attached to one end of the operating shaft, the saidcrank handle is provided with a short laterally extended hub portion R,working against theouter edge of the bearing neck P, and with a squaredto tit over the squared end of opening R', said shaft. The said crankhandle is detachably held in position by means ot the securing screwfr', engaging a threaded opening r2, in the outer end of the shortoperating shaft. The crank handle is turned back and forth in operatingthe pump, it being obvious that the meshing cog pinion will communicateareciprocating motion to the upper rack end of the pump rod and therebyoperate the pump to discharge a quantity of oil out throughthe dischargespout S,1eading from the pump discharge pipe near its upper end.

The short hub portion R, at one end of the crank handle, accommodatesthereon the circularly adjustable stop collar T, provided at one i sidewith a stop-lug t, and a threaded opening t', to receive the set screwt2, which holds the said collar fast` in any adjusted position on thehub of the crank handle, and the movement of said crank handle islimited by the stop lug, t, of said stop collar coming in contact withthe'stop pin U, projecting from one side of the, bearing bracket. Whenthe piston of the pump is raised to itsfull height the lug on saidcollar is` adapted to contact with said pin, and it will therefore beobvious that by adjusting the collar and moving the stop lug thereoftoward or away from'the saidstop pin, the stroke of the pump can be madelonger or shorter, so that the exact amount of liquid to be drawn by acomplete stroke can be accurately regulated or gaged.

At one side of the stop collar T, and adjustably mounted on the bearingneck P, is a secondstop collar V, provided aty one side with a threadedopening fu, to receive a set screw/v', to hold the second stop collarfast on thebearing neckin any adjusted position. The said collar V,isfurther provided with a recessed lug W, Which accommodates thereinthesliding stop stud w, having attachedu to one end thereof the shortfinger wire or piece'w', which is grasped by the fingers to project oneend of the stop stud beyond the outer face of the second stop collar andin the path of the stop lug t, on the main stop collar T, and therebyprovide means for shortening up the stroke to one-half or one quarter,or other fraction desired.

As illustrated, We may assume that the outer or main stop collar T, isadj usted so that one complete stroke of the` piston will draw one halfa gallon, While theinner or second stop collar is adjusted so that whenthe stop stud is projected, the movement of the crank handle will onlygive one half a stroke and thereby pump ono quart o tho liquid; to bodrown With tho honor` operative moohaoiom ad,- J'uotod to sosolooo holoo gallon of liquid at each strokeit will be obvious thatin1 drawinglarge quantities, forinstauce tive gaiionsor more, it would require theoperators closest attention to" count ten or more haii-gallonstrokes,`and torelieve the operator of such ooon and.V to. aoouratolaiodioeto t11o -osooo amountof liquid'being piirnped,i1le1nploy aregister dial X, The register dial X, is mounted on the pivotscrew wc.,at one side of the oft-standing bearing bracket and isoprovided uponitsperiphery with suitable.1 graduations from one gallon up, and alsowith a ratchet portion or disk Y, the teeth ot'` which are engagedoneatl ajtimelat the endot each full stroke by the gravity pawl or,dogg/,pivotally mounted in the recess y', at one` endfof the shortoperatingshaft0,ivvliicli isjournaled below theregister,diai.` A pointerfinger Z,

When the` pumpisadjustedlto operate in connectionwith the inner or second stop collarand its` sliding stop stud, the registering device just` describedishardlynecessary` and will notzoperate."

From the above it will be seenV that the herein-described pump can beaccurately gagedtodraw any amount of liquid desired at one strokeofthepistomwhile at the same time simpleand efficient meansare providedfor oooororoly rogiotorns extra. largo quontities ofI the liquid beingpumped, andlwill haveit understood thatchanges` in the form, proportionand tho minor details ofi ooootruotion may be resortedi to withoutdeparting from the principle orn sacrificing any oi the advantages of;`this invention.
